Added code to check for an adaptec 1542B Version 3.20 Board. This was the
first board that supports >1Gb drives and has the extended bios. So we
need also to disable the exbios like it is done for the 1542C/CF boards.
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.
This also includes support for second-directory compiles. This is not
quite complete yet, as `config' doesn't yet do the right thing. You can
still make it work trivially, however, by doing the following:
rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make
Added my if_lp TCP/IP driver to lpt.c.
I have (surprise) not been able to test it on a 2.0 machine yet. Connect the
machines with a parallel "lap-link" cable, and get rates from 35 kbyte/sec
up to 75 kbyte/sec. (when ftp'ing foo: dev/zero -> bar:/dev/null).
The same lpt.c file should compile under 1.1.5.1 without problems.
I think we should promote this feature when we dump 2.0 on the expectant
public, because it provides a cheap and efficient way to move data to and
from notebooks &c. It is not a replacement for ethernet, but a cheap
substitute sometimes.
This driver supports all the DEC EtherWORKS III NICs (DE203, DE204,
and DE205) and the later DEC EtherWORKS II NICs (DE200, DE201, DE202,
DE422). DEPCA-style boards prior to the DE200 have not been tested
and may not work.

are running under. Here's how to bootstrap (order is important):
1) Re-compile gcc (just the driver is all you need).
2) Re-compile libc.
3) Re-compile your kernel. Reboot.
4) cd /usr/src/include; make install
You can now detect the compilation environment with the following code:
#if !defined(__FreeBSD__)
#define __FreeBSD_version 199401
#elif __FreeBSD__ == 1
#define __FreeBSD_version 199405
#else
#include <osreldate.h>
#endif
You can determine the run-time environment by calling the new C library
function getosreldate(), or by examining the MIB variable kern.osreldate.
For the time being, the release date is defined as 199409, which we have
already established as our target.
use it in NFS. This is required both for diskless support and for POSIX
compliance. Note: the support in NFS is only for the local node.

Reduced maximum transfer size by one to allow for catching a too large
condition correctly. Do single block I/O if the size is too large.
